The vitrification and crystallization temperatures are determined from the changes in the dielectric properties of the condensates upon heating.

The temperature dependence of the solution mean lifetime has been traced at two values of methane concentration (2.1 and 6.0 mol %) and two pressures (1.0 and 1.6 MPa). The results of experiments are compared with classical homogeneous nucleation theory. For pure ethane at small (<8.9 s) lifetimes, one can observe a systematic “under-heating” (0.5–0.7 K) of the solution against theoretical values of the limiting superheating temperature. Dissolution of 6 mol % of methane in ethane results in a solution “superheating” of 0.7 K in excess of the theoretical value. The slopes of experimental curves at small (<8.9 s) lifetimes are in satisfactory agreement with theory. When the mean lifetimes exceed the value of 8.9 s, one can observe considerable deviations of experimental curves from theoretical lines. The discrepancies are discussed in the context of models of heterogeneous and initiated nuc \\\\Expert2\\nbo\\Journal of Physical Chemistry C\\2012, v. 116, p.20458.pdf |

Рубрики: ФИЗИКА Кл.слова (ненормированные): CLATHRATE HYDRATE -- KINETICS -- METHANE Аннотация: Layers of methane-saturated amorphous ice were obtained by deposition of molecular beams of water and gas on a substrate cooled with liquid nitrogen. Their heating is accompanied by glass transition (softening) and subsequent spontaneous crystallization. The avalanche-type initiation of crystallization centers captures the gas molecules and does not lead to their displacement by the motion of the crystallization front. Under crystallization of amorphous water-gas condensates in conditions of deep metastability the formation of gas hydrates takes place. Glass-transition and crystallization temperatures of the condensates were determined by changes in their dielectric properties under heating. The method of differential thermal analysis has been used to investigate the kinetics of crystallization of amorphous water layers. Properties that characterize the water crystallization kinetics have been determined on the basis of the obtained data on the dependence of the crystallization temperature on the heating rate \\\\expert2\\NBO\\International Journal of Heat and Mass Transfer\\2013, v.65, p.649-654.pdf |

The calculated frequency dependence of the real and imaginary parts of the dielectric permittivity points to the prevalence of a high-frequency mode in the spectra of these parameters after methane is adsorbed by water clusters. Such changes are also observed in the spectrum of the IR radiation absorption coefficient; however, the average value of this coefficient remains nearly the same. Methane adsorption causes a considerable increase in the reflection coefficient of the disperse water medium and the integrated power of IR radiation emission \\\\expert2\\NBO\\High Temperature\\2013, v. 51, N 3, p.369-376.pdf |

Рубрики: ФИЗИКА Кл.слова (ненормированные): AMORPHOUS ICE -- GAS HYDRATES -- CARBON DIOXIDE Аннотация: Layers of amorphous ice saturated with methane, ethane, propane and carbon dioxide were obtained by condensation of molecular beams of rarefied vapor and gas on a substrate cooled with liquid nitrogen. The amorphous state of such objects at low temperatures is stabilized by the high viscosity and the small value of the stationary nucleation rate of the crystal phase. Their heating in condition of high metastability is accompanied by spontaneous explosive crystallization, which leads to the formation of gas hydrates. Glass-transition and crystallization temperatures were determined by changes in their dielectric properties under heating. An increase in the gas content in layers of amorphous ice causes an increase in the crystallization temperature without any significant changes in the glass transition temperature. At atmospheric pressure in a liquid n-pentane medium the retention of gas hydrates was observed up to temperatures close to 273. K. Self-preservation ensured the retention of hydrates in a metastable state at temperatures exceeding considerably their equilibrium dissociation temperatures. Samples of gas hydrates obtained at a maximum gas flow rate during the deposition contained up to 15 mass % of methane, 12 mass % of ethane, 13 mass % of propane, and 23 mass % of carbon dioxide \\\\expert2\\nbo\\Chemical Engineering Science\\2015, v.130, p.135-143.pdf |
